Arahan Operasi
To ensure optimal performance and prevent damage, follow these operating guidelines:
- Padanan Kuasa: Pastikan anda amplifier's RMS power output matches the subwoofer's RMS power handling (2000W). While the subwoofer can handle peak moments of 8000W, continuous operation above RMS can lead to damage.
- Padanan Impedans: Always match the final impedance of your subwoofer wiring to the stable impedance load of your amplifier. Mismatched impedance can cause amplifier overheating or subwoofer damage.
- Tetapan Keuntungan: Tetapkan anda amplifier's gain correctly to prevent clipping and distortion. Start with the gain at minimum and slowly increase it until you hear distortion, then back off slightly.
- Tetapan Crossover: Gunakan penapis laluan rendah (LPF) pada anda amplifier to ensure only low frequencies are sent to the subwoofer. A typical LPF setting for subwoofers is between 80Hz and 120Hz.
- Penapis Subsonik: Jika anda amplifier has a subsonic filter, set it to protect the subwoofer from playing frequencies below its resonant frequency, which can cause excessive excursion and damage.

Penyelenggaraan
Regular maintenance helps extend the life of your subwoofer and ensures consistent performance:
- Pembersihan: Keep the subwoofer cone and surround free from dust and debris. Use a soft, dry cloth to gently wipe surfaces. Avoid using harsh chemicals.
- Pemeriksaan: Periodically inspect the speaker terminals, wiring, and cone for any signs of damage, loose connections, or wear.
- Pengudaraan: Ensure the subwoofer enclosure and amplifier have adequate ventilation to prevent overheating, especially during prolonged high-volume use.
- Avoid Over-Excursion: Do not push the subwoofer beyond its mechanical limits, which can be identified by audible distortion or visible excessive cone movement.
